Directional Derivative Calculator

Understanding the Directional Derivative

The directional derivative is a way to measure how a function changes as you move in a specific direction. It gives you the rate of change of the function at a particular point when you follow a direction vector. This concept is useful in many fields, including Physics, engineering, and economics, where it’s important to know how a function behaves in different directions. The directional derivative helps to visualize how functions change, making it easier to analyze complex problems.
